on the parts arm: :1 Jlbl 2111015! the upper i will be Sinai: with The truss; bars; 15 w and W. h and; cook and the he no (ii wide, of rang. and am .1 numbmr munication between g flues at their inner endsf ntt'the transverse protected-by insulating sheets or boards Z and m, of .asbestos or other suitable n1a terial, The heating flues are provided at the bottom with a lining o, of fire brick or other refractory heat absorbing and reflecting material, removably supported between the truss bars 2' on the insulating sheet or board m. At the inner ends of the heating flues the range is provided on each side of and parallel with the central cross bar 79, which forms a partition between the two main parts or divisions of the fire box or combustion chamber, with an outlet flue 2 which is closed at its front end and opens at its rear end into a chimney pipe or connection 1/. Each flue 7) has a closed bottom and sides and is provided at the top, which is located some distance below the top flanges of-the truss bars 2', with a slide or damper 1" for closing communication betwecn it and the adjoining heating flues, ex-

cept at its front or rear end. Each damper is provided at its front end with a handle 8 projecting through the front wall of the range.

As shown in Fig. 3, the truss bars are cut away at their inner ends. below their top flanges above the fiues 29 so as'tdjaffordcom the adjoining heating outlet flue in each part er division'o'f the range. The webs of the truss-bars i on each side of the central truss bar in each part or division of the range are preferably formed with openings, as indicated by dotted lines in Fig. 3, to afford free communication be tween the adjoining heating flues, but the central bar is preferably made without such openings.

Some of the top plate sections f are preferably formed as shown in Figs. 2 and 3,. with pot or kettle openings for quick work, especially in starting before the top has become hot, and these openings are provided with griddles or lids t and reducing rings u. The several sections f of the top are also formed with apertures 11 to permit the escape of inert gas and the ingress of air to the lines when the range is connected with a chimney, as it should be. Some of the sections are formed at the ends adjacent to the burners with air inlet and lighting openings 10, as shown in Figs. 2 and 3, the edges of the sections next to' these openings being beveled, as shown in Fig. 3, so as to direct the flames issuing from the burners and the air entrained therewith, underneath the top plate.

The range is provided at each end with a number of separately-removable burners, Comprising air and gas mixing tubes 00, having flaring or enlarged air inlet openings at their lower ends and opening at their upper ends, which are bent laterally, into the heating flues in the direction of their length and close to the top plate. These tubes are located entirely outside of the range, where they are unaffected by the heat, their upper laterally bent ends being inserted in openings in the end walls of the range and formed or provided, as shown in Figs. 2 and 3, with lugs which engage with the outer ends of said end walls and hold the burners in-place. They are rcmovably secured in place by brackets y, fastened to the ends of the *ange, and clamping bars a, adjustably secured to the brackets by screws or other means! At their lowerends, which are formed or provided with centrally perforated spiders or cross pieces, they are loosely fitted and rest upon the nipples 2 of gas fcocks of a gas supply pipe 4 extending across the end of the range. Disks 5 for adjusting the supply of air admitted into the lower enlarged ends of the mixing tubes :1: are threaded on the nipples 2.

.By the construction and arrangen'u-nt of the burners above described, a Bunsen or hot blue flame is projected in a strong blast through each heating line from end to end thereof in contact with the top plate, the flame spreading laterally, and filling the channels between the longitudinal flanges of the top plate sections.

To facilitate the operation of the gas cocks, rods (3 are pivotally connected at one end with crank arms 7 on the stems of the cocks and extend therefrom to the front of the range, where they are guided in a vertical plate or bar 8 attached to the range and are formed. or 'novided with knobs or handles 9, as shown in Fig. 1. These knobs or handlesare preferably grouped in a vertical series at each end of the range within clear view and convehicnt reach of the operator, thereby not only facilitating the oj'ieration of the gas cocks but also indicating at a glance which of them are open and which closed.

In the present case the range, as shown by the drawing, has two burners to each heating fine or section of the fire box or chamber, except the rear fl lie or section, which has but one, and the sections 7' of the top plate covering said flues are formed on the under side with a middle rib or flange 10 parallel with the marginal flanges f/ and forming therewith channels fof'conlining and directing the flames and heated products of combustion of the several burners. The top sections f, covering the flue space above the dampers I, are preferably arranged lengthwise thereof and transversely to the other sections covering the heating fines or fire box sections, and do not have ribs or flanges along the middle and the sides next to the heating flues, but are formed with end flanges, as shown in Figs. 3 and To admit an additional supply of air to the several heating fines or sections of the sev- 1.011 hwrein T'mvn am late seehenst J 'pl vi @11 3 and i dle and zu eunetru meat ion the mi 1:;
